type
The types of fag cylindrical roller bearings are divided according to their different retaining forms. The outer ring of Nu type bearing has two retaining edges, and the inner ring has no retaining edge. The inner ring of n-type bearing has two retaining edges, and the outer ring has no retaining edge.
Nu and N cylindrical roller bearings are used for floating ends. The outer ring of NJ cylindrical roller bearing has two retaining edges, and the inner ring has retaining edges, which can bear axial force in one direction.
The spare fixed end of NUP cylindrical roller bearing can bear axial forces in two directions.
Centering
The modified contact line between roller and raceway of fag cylindrical roller bearing can reduce the stress concentration. The allowable deflection angle of single row cylindrical roller bearing is 4 '.
tolerance
The manufacturing tolerance grade of fag cylindrical roller bearing is ordinary grade.
Clearance
Fag cylindrical roller bearings are manufactured with clearance grade of ordinary grade.
Allowable speed
In some cases, the reference speed may exceed the limit speed. Specific working conditions are considered by measuring the heat generated at allowable working speed.
